/**
 * #6700 — Dokploy (and some other self-hosted) Docker builds ended up with a
 * broken/mismatched better-sqlite3 native binding under npm 11. The `builder`
 * stage installed dependencies with `npm ci --ignore-scripts` (deliberate — it
 * closes the supply-chain surface where a transitive dep's install script runs
 * arbitrary code) and then re-enabled the native build for the one package that
 * needs it via `npm rebuild better-sqlite3`. `npm rebuild` re-runs the package's
 * own install script indirectly, which depends on npm's script-allowlist
 * machinery correctly re-enabling that single package's script — some
 * self-hosted build environments hit a broken build via that indirection.
 *
 * Fix: invoke `node-gyp rebuild` directly inside `node_modules/better-sqlite3`,
 * bypassing npm's script-running layer entirely, so the compile step is
 * deterministic regardless of npm version or ignore-scripts allowlist behavior.
 *
 * This guards the mechanism (the direct node-gyp invocation replaces the
 * `npm rebuild` indirection, and a smoke-load still follows it); the end-to-end
 * "the Dokploy build now produces a working binding" proof is a successful
 * `docker build` in that environment (tracked as a live-validation follow-up —
 * this sandbox has no accessible Docker daemon to run the real build).
